standard footprints

[James]

I'm hoping someone can give a noob some direction here. I've started
designing a pcb using electronics workbench and am a bit confused on how to
get past where I am.

I'm trying to create a component for a lumberg part (2415_01, 1502_01 and
2410_01) which are upright (vertical) usb, IEEE1394 and 2.5mm jack
connectors. When creating a new component it gives me a option of choosing a
standard footprint. I can't find a listing of these and I find one that
works with this. I also can't see where to create a new footprint.

Any help is GREATLY appreciated

Thanks,

Return it for full refund. That would be a good start.

It's probably easiest to grap a jack footprint and save it under a

new part name in a library of your own where a reinstall won't wipe
it out and then edit it.

Something tells me you're not going to find many EWB users around. I
might remember one user who didn't bad mouth EWB, but he's probably
commited suicide by now.

Thanks for the feedback - I also have access to powerpcb - is that much
better?

There are two things I need in a pcb design package - easy ability to
create custom decals/footprints as I am using some very specific parts
and secondly I need to overlay a CAD drawing of the board as I need to
be VERY specific in the layout of the components. Its a double sided
board so two cad drawings would be perfect.

Products like Eagle just don't suppor this sort of thing (that I've
foudn so far)

Any thoughts on what I should be using?

Dunno. I'm spoiled.

You might get away with Orcad (cadence) Layout. You can get a
student version and I don't think the limitations will hurt you. I
don't recall the Layout limitations.

The overlay you refer to is know as the silkscreen layer. You can
also do an outline layer and create custom layers.

Terry Pinnel has a page on CAD programs you should check. If he
doesn't chime in soon, I think the URL is something like

www.terrypin.dial.pipex.co.uk and part of that googled ought to
return the URL if I'm wrong.

I also need the silkscreen layer but that's separate. I was referring to

the outline layer. The problem is most entry level progs don't let you
import files for the layers.

Other progs don't let you specify the location of the components
precisely outside of the 2.54mm grid.

Terry: Where are you buddy! Help me ! LOL

Eagle will let you do most of that out of the box (so to speak). It does

do custom footprints (and various silkscreen layers). I found it easy to
create a new package. Weakness on new package layouts, circular holes
only for through hole (If you need a slot you have to build it up).
There are probably other weakness but for straightforward double sided
boards I doubt you will notice.

As far as CAD overlay. There is support in Eagle to allow it but how
easy it is to do I don't know. Check out the DXF importing utilities on
their website (they also have support newsgroups). I think it should be
possible to import a dxf into an unused layer and use that as a guide,
but I haven't done it. Ask in their support newsgroups someone may have
done it.

I also need the silkscreen layer but that's separate. I was referring to
the outline layer. The problem is most entry level progs don't let you
import files for the layers.
Again check for DXF import utilities on Cadsofts support area. There

is/are some image import utility/ies as well but I didn't much care for
the result lasr time I tried.

Other progs don't let you specify the location of the components
precisely outside of the 2.54mm grid.
I've not had a problem with placing on as fine a grid as is unreasonable.

(and in fact you can also position using absolute coordinates from the
keyboard, very useful when trying to match existing mechanicals)

What you are looking for is any package that imports DXF's (or DWG's).
Do mechanical in mechanical, electriconic in electronic.

Import you board outline, slots, and other sundry non electronic component
pcb holes etc.,from a mech. cad package (Autocad or a clone) as one layer.
Do your 'tronic work on other layers - however many you need.

Lots of cad packages do this. They are not expensive.
See Terry Pinnells website for a mega list of 'tronic cad and download some
demo's.
EasyPC will do all you need here for about $160 but there are loads more.
Do not spend a fortune on an 'all singing all dancing' package if you are
not going to use it regularly - you will spend hours, days, weeks, every
time just trying to figure out how to do something in some of the more
complex packages such as Cadstar, Pads etc.
If you use them very regularly they are good otherwise they are worse than
hopeless.

I know - thats what I asked about

Everything is done in cad - solidworks actually as that's what I have
access to. My problem is the ecad part

Pulsonix allows DXF files to be imported into PCBs and PCBs can be exported
as DXFs:

Footprints are very easy to create.

I believe "PinelL" has two els, and that the web page you were
thinking of is the following:

These are just my beliefs: I may be misguided. <g>

2 ens and 2 els, but I think I had his home page right. Should find

links there, but ECADEList.html or htm looks right.

As I said b4:
In solidworks determine the pcb outline (including any non electronic
components slots, holes, etc) then just export it to the e-cad package as a
dxf.
This is your board ouline layer which you never need touch - just leave it
all alone on its own layer and do the other e-cad on other layers.
Loads of e-cads import dxf's and solidworks exports them.
